This is my bind code:
<div id="exam-passing-test">
<button id="button-next-task">
<div class="e-div-nextpage-style">'.$butText.'</div>
</button>
</div>
function($){
$.event.special.destroyed = {
remove: function(o) {
if (o.handler) {
o.handler()
}
}
}
})(jQuery);
$("#exam-passing-test").on("destroyed", function() {
console.log("bind")
alert("Error");
});
$("#button-next-task").on("click", function(e){
e.preventDefault();
$("#exam-passing-test").off("destroyed", function() {
console.log("unbindOk")
});
$("#content-exam").load("/exam.php?action=show&epage=task&categoryId=" + selectedCategoryId, {testData:testData});
)};
Ok, now i just try to do that, I simplified the code, but off still not working. Need to off() event on click button.
Consider using jQuery.one() method:
$( "#exam-passing-test" ).one( "click", function( event ) {
alert( "A click event happened!" );
});
It will handle your click event just once.

Is it possible listen click and change for one code?
$(document).on("click", "button.options_buy",function(event) {
// same code
}
$(document).on("change", "select.options_buy",function(event) {
// same code
}
I try this
$(document).on("click change", "button.options_buy,select.options_buy",function(event) { }
It works but I want 'click' only for 'button.options_buy' and 'change' for 'select.options_buy'
is it possible?
Best way to do it is to have two event handlers as you have, but only have a common function that is called from each:
$(document).on("click", "button.options_buy",function(event) {
commonFunction();
})
$(document).on("change", "select.options_buy",function(event) {
commonFunction();
})
function commonFunction(){
//common function code
}
I would like to extend your code.
$(document).on("click change", "button.options_buy,select.options_buy",function(event) {
if(event.type=="click"){
someFunction();
} else if(event.type=="change"){
someFunction();
}
}
You can use .on() to bind a function to multiple events:
$('#foo').on('keypress click change', function(e) {
//
});
OR declare a function and call it for each event
$('#foo')
.change(myFunction)
.click(myFunction)
.blur(myFunction)
jQuery .bind()
$( "#foo" ).bind({
click: function() {
// Do something on click
},
mouseenter: function() {
// Do something on mouseenter
}
});
OR
$( "#foo" ).bind( "mouseenter mouseleave", function() {
$( this ).toggleClass( "entered" );
});
I am trying to apply a new Style to my Submit-Button if its focused.So if its focused, the Style changes, but i cant get rid of it.Means that i cant lose focus on my Button.The other Problem is, that when focused the button moves like 2-3pixel down.
$(document).ready(function(){
$(".login").hover(function() {
$(this).toggleClass("hoverbutton");
});
$(".login").focus(function(){
$(this).toggleClass("focusbutton");
return false;
});
});
Hope someone can help me out with this :)
try this
$(document).ready(function () {
$(".login").hover(function () {
$(this).toggleClass("hoverbutton");
}, function () {
$(this).toggleClass("Normalbutton");
});
});
OR
$(document).ready(function () {
$(".login").hover(function () {
$(this)
.removeClass("normalbtn")
.addClass("hover_btn");
}, function() {
$(this)
.removeClass("hover_btn")
.addClass("normalbtn");
});
});
Refer Here
According to the jQuery API (http://api.jquery.com/hover/), hover accepts two functions:
$( ".login" ).hover(
function() {
// This part is called on Mouse over
$( this ).addClass( "hoverbutton" );
}, function() {
// This part is called on Mouse out
$( this ).removeClass( "hoverbutton" );
}
);
$(".login").blur(function(){
$(this).removeClass("focusbutton");
return false;
});
Added this after .focus() and works fine for me
You are looking for wrong events,
Look at jQuery API: http://api.jquery.com/blur/
I have this JQuery code:
function JQueryPopup(value) {
$(value).toggle();
$('#JQueryClose').click(function(){
$(value).hide();
});
$( document ).on( 'click', function ( e ) {
$(value).hide();
});
$( document ).on( 'keydown', function ( e ) {
if ( e.keyCode === 27 ) { // ESC
$(value).hide();
}
});
}
and a HTML button that calls this function, it doesn't seem to be showing the popup window/div.
here is a fiddle with my full code: http://jsfiddle.net/XHLY8/3/
P.S. i do have this code on another page, i call the function like this:
<script type="text/javascript">JQueryPopup('#customer_popup_notes');</script>
which works fine.
You need to add the following:
$('#inbox_button').on('click', function(event){
event.preventDefault(); // This isn't critical, but you would need
event.stopPropagation();
JQueryPopup('#inbox_div');
});
You want to stop the click event from bubbling up and triggering the following:
$( document ).on( 'click', function { ... });
Otherwise your #inbox_div will be hidden before you can see it.
Here is a working fiddle.
I suggest reading up on stopPropagation and preventDefault.
You dont need
$( document ).on( 'click', function ( e ) {
$(value).hide();
});
Which always hides the Bottom div no matter where u click .

How can I temporary disable onclick event until the event is finished?
So far that's all I've come up with:
<script>
function foStuff(a){
//no modifications here to be done, just some code going on
}
$(document).ready(function(){
$("#btn").click(function(){
var obj = $(this);
var action = obj.prop('onclick');
obj.prop('onclick','');
whenDoStuffFinishes.(function(){ //when do stuff finishes is what i need to get
obj.prop('onclick',action);
});
});
});
</script>
<div id="btn" onclick="doStuff(500)">
</div>
EDIT:
I've tried it this way: but it doesn't unblock the click event
$("#btn").click(function(){
var obj = $(this);
obj.off('click');
$.when( doStuff(500) ).then( function(){
obj.on('click'); // it actually comes here, but click event is being unset
} );
});
<script>
$(document).ready(function(){});
</script>
<div id="btn">
</div>
Well, you can create a variable that tells your function to ignore it while it's true;
var isIgnore = false;
$("#btn").click(function(){
if(isIgnore)
return;
isIgnore = true;
var obj = $(this);
var action = obj.prop('onclick');
obj.prop('onclick','');
whenDoStuffFinishes.(function(){
obj.prop('onclick',action);
isIgnore = false;
});
});
This code is not tested but I think this will work.
Simply reference the handler, and detach it before performing your action, then at the end attach it again ...
$(document).ready(function () {
var handler = function () {
var obj = $(this);
obj.off('click');
whenDoStuffFinishes.(function () {
obj.click(handler);
});
};
$("#btn").click(handler);
});
use pointerEvents.try this:
$("#btn").click(function(){
document.getElementById('btn').style.pointerEvents = 'none';
whenDoStuffFinishes.(function(){
document.getElementById('id').style.pointerEvents = 'auto';
});
});
Using a combination of bind and unbind
https://api.jquery.com/bind/
https://api.jquery.com/unbind/
Turn the event off once it is triggered and reattach it at the end of the callback.
jQuery( '#selector' ).on( 'click', function voodoo( event ) {
jQuery( event.target ).off( event.type );
// Do voodoo...
jQuery( event.target ).on( event.type, voodoo );
});
Alternatively and depending on the scenario, event.stopImmediatePropagation() might also serve as a solution. It will stop all subsequently attached event handlers from firing and itself from bubbling up the DOM tree.
jQuery( '#selector' ).on( 'click', function( event ) {
event.stopImmediatePropagation();
});
I'm changing my codes to be compatible with jQuery 1.8 and I'm stuck with this hover which doesn't work. When I used then same thing with a click it worked. Here is my code, can anyone tell me where I'm going wrong?
$(document).on('hover', '.top-level', function (event) {
$(this).find('.actionfcnt').show();
$(this).find('.dropfcnt').show();
}, function () {
$(this).find('.dropfcnt').hide('blind', function () {
$('.actionfcnt').hide();
});
});
Deprecated as of jQuery 1.8: The name "hover" used as a shorthand for the string "mouseenter mouseleave". It attaches a single event handler for those two events, and the handler must examine event.type to determine whether the event is mouseenter or mouseleave. Do not confuse the "hover" pseudo-event-name with the .hover() method, which accepts one or two functions.
Source: http://api.jquery.com/on/#additional-notes
That pretty much says it all, you cant use "hover" for that:
$(document).on('mouseenter','.top-level', function (event) {
$( this ).find('.actionfcnt').show();
$( this ).find('.dropfcnt').show();
}).on('mouseleave','.top-level', function(){
$( this ).find('.dropfcnt').hide('blind', function(){
$('.actionfcnt').hide();
});
});
there is no "hover" event.
there is .hover() function that takes 2 callbacks (as in your example).
Try:
$(".top-level").on({
mouseenter: function (event) {
$( this ).find('.actionfcnt').show();
$( this ).find('.dropfcnt').show();
},
mouseleave: function (event) {
$( this ).find('.dropfcnt').hide('blind', function(){
$('.actionfcnt').hide();
});
}
});
OR
$(".top_level").on("hover", function(event) {
if(event.type == "mouseenter") {
$( this ).find('.actionfcnt').show();
$( this ).find('.dropfcnt').show();
}
else if (event.type == "mouseleave") {
$( this ).find('.dropfcnt').hide('blind', function(){
$('.actionfcnt').hide();
});
}
});
.on function has only 3 parameters : http://api.jquery.com/on/
If you don't need your handlers be bound to dynamically added elements as well, then you may use the good old hover function with 2 event handlers.
$('.top-level').hover(function (event) {
$(this).find('.actionfcnt').show();
$(this).find('.dropfcnt').show();
}, function (event) {
$(this).find('.dropfcnt').hide('blind', function(){
$('.actionfcnt').hide();
});
});
By the way, $(selector).hover(handlerIn, handlerOut) is shorthand for $(selector).mouseenter(handlerIn).mouseleave(handlerOut);.
If you need to, then use on for mouseenter and mouseleave events:
$(document).on('mouseenter', '.top-level', function (event) {
$(this).find('.actionfcnt').show();
$(this).find('.dropfcnt').show();
}).on('mouseleave', '.top-level', function (event) {
$(this).find('.dropfcnt').hide('blind', function(){
$('.actionfcnt').hide();
});
});
Try
$('.top-level').hover(function (event) {
$( this ).find('.actionfcnt').show();
$( this ).find('.dropfcnt').show();
}, function(){
$( this ).find('.dropfcnt').hide('blind', function(){
$('.actionfcnt').hide();
});
});
